Abstract
The invention relates to a sheet material and a production process, and belongs to the technical field of building finishing materials.The sheet material comprises the following raw materials by weight: 60-75% of plant straw, 15-30% of waste plastics, and 10-20% of flame retardant materials. The manufacturing method comprises the following steps: 1) crushing the plant straw; 2) crushing the waste plastics; 3) blending materials; 4) stirring and mixing; 5) adding the mixed raw materials into a waste plastic granulator for heating and extrusion; 6) performing extrusion molding in a hydraulic or mechanical press; 7) cutting in a cutting machine to obtain the required finished product specification. The production process of the invention has wide raw material sources and low cost, and changes wastes into valuables; the finished product has good heat insulation, waterproof and processing performance; and the price of the finished product is much lower than that of wood and other sheet material substitutes. The sheet material of the invention can be used as building materials and decoration and finishing materials, and also can be used for manufacturing industrial or daily articles.
Description
Technical field
The present invention relates to a kind of sheet material and production technique thereof, belong to the constructional ornamental material technical field.
Background technology
The Along with people's growth in the living standard, the requirement that people improve housing conditions is strong further, thereby construction industry and decorative craft are also increasing to the demand of sheet material; And our area of woods of institute's inhabitation earth is fewer and feweri, and timber resources appears global in short supply, so a large amount of wood substitutes of many enterprises exploitation; Like shaving board, high density fiberboard etc.; But its production cost of these products is all than higher, and the production cycle is longer, thereby causes building and the increase of decoration cost.
Summary of the invention
The objective of the invention is to solve the deficiency that above-mentioned prior art exists, a kind of sheet material and production technique thereof of utilizing various nontoxic waste or used plastics and straw to produce is provided.
The present invention realizes through following technical scheme:
A kind of sheet material is characterized in that raw material comprises following component, is respectively by the weight percent of each component: straw 60-75%, waste or used plastics 15-30%, fire retardant material 10-20%.
Said straw is that a kind of agricultural crop straw or several kinds of agricultural crop straws mix or wild grass or agricultural crop straw mix with wild grass.
Said waste or used plastics is nontoxic waste or used plastics, like Vilaterm, SE, gather one or more mixing in the nontoxic waste or used plastics such as third ethene.
Said fire retardant material is talcum powder or stone powder or light calcium carbonate.
The production technique of above-mentioned sheet material is characterized in that may further comprise the steps:
1) straw is pulverized: adopt kibbler that straw is ground into more than granularity 60 orders to 10mm;
2) waste or used plastics is pulverized: waste or used plastics is crushed to granularity less than 10mm;
3) batching: take by weighing straw, waste or used plastics and fire retardant material after the pulverizing respectively by formula rate;
4) mix: the raw material that will take by weighing is sent into stirrer and is mixed;
5) mixed raw materials is added the waste plastic granulation machine and heat and extrude, used waste plastic granulation machine die head and dicing machine are removed need not;
6) get into hydraulic pressure or mechanical press extrusion molding;
7) send into cutting machine and cut into desired trimmed size.
Beneficial effect of the present invention: raw material sources of the present invention are extensive, with low cost; Turn waste into wealth, its production technique is easy rationally, easy handling; Its finished product has good insulation, waterproof and processing characteristics; It is incomparable with other sheet material substitute that its waterproof effect and anticorrosion effect are any planks, but in the long period of soaking water and do not deform and corrode, and the finished product price is well below timber and other sheet material substitute.Can be used to as material of construction and decorating and renovating material, also can be used to make industry or daily necessities.
Four, embodiment
Below provide embodiment of the present invention, be used for formation of the present invention is further specified.
Embodiment 1
A kind of sheet material of present embodiment is characterized in that raw material comprises following component, is respectively by the weight percent of each component: straw 60%, waste or used plastics 25%, fire retardant material 15%.
Straw all adopts wheat stalk.
Waste or used plastics is the Vilaterm waste material.
Fire retardant material adopts talcum powder.
The production technique of above-mentioned sheet material is characterized in that may further comprise the steps:
1) straw is pulverized: adopt kibbler that straw is ground into more than granularity 60 orders to 10mm;
2) waste or used plastics is pulverized: waste or used plastics is crushed to granularity less than 10mm;
3) batching: take by weighing straw, waste or used plastics and fire retardant material after the pulverizing respectively by formula rate;
4) mix: the raw material that will take by weighing is sent into stirrer and is mixed;
5) mixed raw materials is added the waste plastic granulation machine and heat and extrude, used waste plastic granulation machine die head and dicing machine are removed need not;
6) get into hydraulic pressure or mechanical press extrusion molding;
7) send into cutting machine and cut into desired trimmed size.
Embodiment 2
A kind of sheet material of present embodiment is that with embodiment 1 difference raw material comprises following component, is respectively by the weight percent of each component: straw 70%, waste or used plastics 20%, fire retardant material 10%.
Straw is 20% wheat stalk and 50% corn straw.
Waste or used plastics is SE, gather waste or used plastics such as third ethene.
Fire retardant material adopts the stone powder.
Embodiment 3
A kind of sheet material of present embodiment is that with embodiment 1 difference raw material comprises following component, is respectively by the weight percent of each component: straw 75%, waste or used plastics 15%, fire retardant material 10%.
Straw is 30% corn straw, 15% wheat stalk and 30% wild grass.
Waste or used plastics is waste or used plastics such as SE, Vilaterm.
